here is what i have told members of my alliance to do. it seems to work
the hardest medals to find are rose, honor, and freedom, or so it seems.
so for rose i say 300 archers on a level 3 forest. seemed to work best for me.
honor 400 balls on a level 4 npc, hit it every hour
freedom, 500 balls on a level 5 npc, hit it every 6 minutes
and justice, because you just need too many of them, send a spearhead followed by 5 waves of 100k warrs at a level 10 npc. seems like the first 6 hits have a higher chance of getting medals for 10s
